Migratory Bird Hunting; Revision of Language for Approval of Nontoxic Shot for Use in Waterfowl Hunting

Riepilogo

We, the U.S. Fish and Wildlife Service, revise our regulations regarding the approval of nontoxic shot types to make the regulations easier to understand. The language governing determination of Estimated Environmental Concentrations (EECs) in terrestrial and aquatic ecosystems is altered to make clear the shot size and number of shot to be used in calculating the EECs. We specify the pH level to be used in calculating the EEC in water. We also move the requirement for in vitro testing to Tier 1, which will allow us to better assess applications and minimize the need for Tier 2 applications. We add language for withdrawal of shot types that have been demonstrated to have detrimental environmental or biological effects, or for which no suitable field-testing device is available. We expect these changes to reduce the time required for nontoxic shot approvals. Finally, we add fees to cover our costs in evaluating these applications.
